Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583670, here are decompositions:

7 + 31583663 = 31583670
11 + 31583659 = 31583670
29 + 31583641 = 31583670
37 + 31583633 = 31583670
43 + 31583627 = 31583670
73 + 31583597 = 31583670
109 + 31583561 = 31583670
149 + 31583521 = 31583670

Showing the first eight; more decompositions exist.
